In the ALV list tree

use call method CALL_ITEM_METHOD OF CL_GUI_LIST_TREE class

Use method item_free where item is object CL_GUI_OBJECT class

In the CLASS CL_GUI_ALV_TREE

there is method refresh_table_display

Please reward if useful.

hi

good

go through this code

Declare table to store top leve nodes in top include

types: begin of t_topnodes,

nodekey type lvc_nkey,

end of t_topnodes.

data: it_topnodes type standard table of t_topnodes,

wa_topnodes like line of it_topnodes.

Add code to build top level node table

data: ls_sflight type sflight,

lt_sflight type sflight occurs 0.

data: ld_ebeln_key type lvc_nkey,

ld_ebelp_key type lvc_nkey.

loop at it_ekko into wa_ekko.

perform add_ekko_node using wa_ekko

''

changing ld_ebeln_key.

wa_topnodes-nodekey = ld_ebeln_key.

append wa_topnodes to it_topnodes.

loop at it_ekpo into wa_ekpo where ebeln eq wa_ekko-ebeln.

perform add_ekpo_line using wa_ekpo

ld_ebeln_key

changing ld_ebelp_key.

endloop.

endloop.

• calculate totals

call method gd_tree->update_calculations.

• this method must be called to send the data to the frontend

call method gd_tree->frontend_update.

data: ls_gmsec type zgmsec,

ld_answer type c.

case fcode.

when 'CHNG'.

data: ld_uname type zgmuserparam-uname.

data: lt_selected_node type lvc_t_nkey.

call method tree1->get_selected_nodes

CHANGING

ct_selected_nodes = lt_selected_node.

call method cl_gui_cfw=>flush.

data l_selected_node type lvc_nkey.

check not lt_selected_node[] is initial.

read table lt_selected_node into l_selected_node index 1.

call method tree1->get_outtab_line

EXPORTING

i_node_key = l_selected_node

IMPORTING

e_outtab_line = ls_gmsec.

if ls_gmsec-uname is initial.

message i010(ad) with 'Please choose a valid user'.

else.

• Example: i.e calls screen to allow user to make chnage

call screen 0300.

• AT this point user has returned from a screen (i.e. 300) which

• allowed them to make changes to existing data/node

• The following code deletes all the existing nodes using the top

• node table populated earlier

loop at it_topnodes into wa_topnodes.

call method TREE1->DELETE_SUBTREE

EXPORTING

i_node_key = wa_topnodes-nodekey.

endloop.

call method cl_gui_cfw=>flush.

• Now you need to re-select your data and re-build your hierarchy

• from scratch. for example the code could look somthing like this.

REFRESH: it_ekko, it_ekpo.

SELECT ebeln

UP TO 10 ROWS

FROM ekko

INTO corresponding fields of TABLE it_ekko.

loop at it_ekko into wa_ekko.

SELECT ebeln ebelp statu aedat matnr menge meins

netpr peinh

FROM ekpo

appending TABLE it_ekpo

where ebeln eq wa_ekko-ebeln.

endloop.

perform create_alvtree_hierarchy.
